LACING FASTENING.

Application flled' August 25, 1927, Serial No. 215,497, andiu GermanyJune 30, 1927.

form a support about which the laceend can he looped, the-armsbeing.spring-controlled and adapted to he closed and retained in closedposition by means of a shackle.

Fig. 1 of the accompanying dra *ings represents a front view of thedevice in closed position,

Fig. 2, a view of the same showing the open position, i

Fig. 3, a side view of "a device having two pairs of fastening arms anda pivoted retaining shackle,

Fig. 4, a top view, partly in section, of H Fig. 3,

Fig. 5, a front view. of the same, and

Fig. 6, a view illustrating the principle on which the fastener isconstructed.

Referring to Fig. 6 which shows a lace 7o looped about a rod m, it willhe evident that a pull on either end of the lace 70 will secure thelatter all the tighter to the rod instead of detaching it from the same.However, even if the lace is very firmly tightened to the rod in thismanner, the detachment of the lace can easily be effected by pulling therod out of the loop. i

The lacing fastening accordingto the pres mt invention operates on thisprinciple.

"The rod m is replaced by two corniform lever arms, such as c in Fig. l,which are pivoted to a stud a or the like. the latter, which need not belarger than'one of the usual lacing hooks applied to hoot-s andshoes,heing secured as the final'lace holder to the laced article. The armsare spring-pressed and tend to open out as shown in Fi 2. For

fastening the lace, the end of the latter is looped as shown in Fig. 1,and the arms are closed so that the points meet inside the loop andform, like the rod m, a continuous sup port about which the loop can betightened under the tension of the lace. For closing the arms andretaining them in closed position, a shackle g may he used which isitself-retained on the arms by snapping into notches i in the latter.One arm may have a point a adaptedto enter a corresponding recesso atthe end of the other arm so as to 1 prevent relative displacement of theclosed arms. I

To undothe fastening the shackle g is re moved, whereupon the arms canbe separated however tightly the loop should happen to be secured.

Two pairs of arms, 0 and cl, may he mounted on the same stud, as shownin Figs. 3 and 4. for connection to different ends of the lace.

In this case two shafts Z are employedeach of which carries two armscontrolled by a single spring f. The closing and retaining shackle (7 ispivoted to the stud (I so that it can he turned into and out ofoperative position.

I claim:

.A lacing fastening col'uprising a support, two pa 'allel distancedshafts mounted in. said support, corniilorm lever arms secured to theends of said shafts so that the arms can he closed in pairs point topoint, a spring tending to open the arms, and a shackle adapted toembrace a pair otarms and. to snap into notches in the same forretaining the arms in closed position, the shackle being pivoted to thesupport so as to allow of being turned into and out of operativeposition.
